**rjrey109**: hey

**rjrey109**: how did u draw the iterations?

**emozemoz**: enter the equation in the top bar on hte progrram and hit enter

**rjrey109**: u mean x-y1/nderivy1?

**emozemoz**: no

**emozemoz**: the actual function

**emozemoz**: like 4x-9

**rjrey109**: yeah..but then when u want to draw the iteration of it

**emozemoz**: ok they give you the first value right?

**emozemoz**: then you find the derivative of the function at that point

**rjrey109**: yeah

**emozemoz**: find the zero of the tangent line at that point

**rjrey109**: how do u do that?

**emozemoz**: find the derivative of the original function

**emozemoz**: then plug the x value in

**rjrey109**: ok

**rjrey109**: so run thru 1a for me

**rjrey109**: just as an example

**rjrey109**: i put in x2-3

**rjrey109**: and it draws a parabola

**emozemoz**: x0=2.2

y0=1.84

f(x)=x^2-3

f'(x)=2x

f'(x)=4.4

eq of tan line at (2.2,1.84): y=4.4x-7.84

x1=7.84/4.4=1.7818

x1=x0-f(x)/f'(x)

x1=x0-(x0^2-3)/(2*x0)

x1=2.2-(2.2^2-3)/(2*2.2)=1.7818

------

x1=1.7818

y1=.1748

f'(x)=2x

f'(x1)=3.5636

eq of tan line at (1.7818,.1748): y=3.5636x-6.1748

x2=x1-(x1^2-3)/(2*x1)

x2=1.7327

y2=.0024

**emozemoz**: yeah

**emozemoz**: that's all of numver one

**emozemoz**: but hey i gotta get back to typing my extended essay, srry

**emozemoz**: here's the rest of my work h/o

**rjrey109**: whoa

**rjrey109**: ok

**emozemoz**: http://www.xanga.com/home.aspx?user=balasubasngkamatayan

**emozemoz**: later

**rjrey109**: later

**rjrey109**: 1 quick question though

**Auto response from emozemoz**: bizzy

**rjrey109**: how do u save the graph?

**emozemoz**: print screen and paste to paint

**rjrey109**: k thanx

**Auto response from emozemoz**: I am away from my computer right now.
